5.6.2.3. Frequency spectrum analyzer

Fig. 5.46: Menu Tools / Live Data / Frequency spectrum analyzer
A very useful tool for identifying in-band interference and locating a free channel. It is not a full-blown
spectrum analyzer as it scans the spectrum with 2 MHz channel resolution. The accuracy of measured
results is given by the accuracy of measuring RSS.
